Gamma- High energy rays with short waves.Who wants to go for a swim? Or nah?-Possibility of contracting Naegleria Fowleri which is a disease that eats away at brain tissue and commonly found in stagnant water-Drowning. To prevent drowning, use floaties.Tritium - what is it?-Tritium is a radioactive isotope of hydrogen-Has a half life of 12.3 years-Emits beta radiationThe effects and concerns of tritium levels in Lake AnnaBy John Crowley, Andre Winchell, & Ethan Flora3 Types of Radioactive DecayAn atom is composed of a nucleus of Protons (positive charge) & Neutrons (negative charge) with orbiting electrons that are negatively charged Effects of Alpha radiation -External exposure (outside body) is virtually harmless-Lack the energy to penetrate the dead layer of skin

-Internal exposure (inside body) by ingesting or being absorbed into your blood stream can cause a risk of developing cancer Effects of being exposed to Beta Radiation-Two types of effects Acute and Chronic

-Chronic Effects are much more common

-Low levels of external exposure over a long time (5-30 years) can cause Cancer

Effects of Exposure to Gamma Radiation-Because of its power and ability to travel long distances Gamma Radiation is very dangerous

-Gamma radiation exposure also causes Radiation sickness

-The worst kind of Radiation damage comes from Gamma Radiation exposure IsotopesIsotopes are formed when the proton neutron balance is uneven, making the atom unstable. Tritium levels in Lake Anna from one sampling point are 53,300 picocuries per liter. The EPA allows up to 20,000 picocuries of tritium per liter. Tritium emits alpha radiation which is harmless for the most part unless ingested or swallowed as it lacks the energy to penetrate skin.Other DangersOther Types of IsotopesCaesium 135-Half life: 2.3 million years-Mildly radioactive-Low energy beta radiationIodine 129-Half life: 15.7 million years-Low energy beta & gamma radiationCaesium 137-Half life of 30 years-Strong gamma radiation-One of the most common fission productsPlutonium 239-Half life: 24,000 years-One of three main isotopes of PlutoniumStrontonium 90-Half life: 28 years-Beta decay-Used in medical researchWhat is Radiation?
